The trial of ESS Chemicals factory owner Suleman "Solly" Lachporia and his manager was on Tuesday postponed to November in the Lenasia regional court. They face a main charge of culpable homicide relating to the death of 11 employees including the supervisor who were killed while on night shift in Lachporia's factory in Lenasia, south of Johannesburg, in November 2000 when a fire swept through the premises in which they were locked.
